• Microwire Serial Interface
• Low Voltage Operation (2.7V)
• Self-Timed Write Cycle
• Write Enable Pin for Protection
• High Reliability
• Small Package Options (SOIC, TSSOP)

Benefits

• Provides non-volatile storage for small amounts of data, such as configuration settings or serial numbers.
• Simplifies interfacing with microcontrollers using a three-wire Microwire interface.
• Reduces power consumption in portable and battery-powered applications.
• Eliminates the need for external timing components during write operations.
• Prevents accidental data overwrites with the write enable pin.
• Ensures long-term data retention and reliable operation.
• Suitable for space-constrained applications due to its small package options.

Additional Details

The AT93C46-10SI-2.7 is commonly used to store configuration parameters, calibration data, or other small amounts of non-volatile information in a variety of applications. The Microwire interface (SI, SO, SK, and CS) allows for easy communication with microcontrollers. The self-timed write cycle simplifies the write process, and the write enable (WE) pin provides hardware protection against accidental data corruption. The low voltage operation makes it suitable for battery-powered devices. This EEPROM is a reliable and cost-effective solution for storing small amounts of non-volatile data in embedded systems. Detailed specifications including timing diagrams, addressing information, and electrical characteristics can be found in the Atmel (Microchip Technology) datasheet.
